What is the difference betwee an LCD and LED TV?

I wear hearing aids because I have a hearing disability, I don’t know if one of them affects the ability to slow down closed captioning, but non-delayed closed captioning is very important to me as well as the quality of the TV itself, so basically I have a few questions; what the difference between them is, What brand of TV is recommended? and Should I get a surround system with it? If so, what do you suggest? Thanks in advance!
I mean between, sorry for the misspelling guys
I too have a hearing loss and enjoy my surround sound when the guy that lives downstairs isn’t home. He bitches when the TV is lower in volume than the heating system.
LED TV’s ARE LCD TV’s. The difference is that LCD TV’s are back lit by what amounts to florescent bulbs. LED TV’s have an array of usually hundreds of LED’s lighting the screen. Some are Dynamic LED TV’s meaning that they change the brightness of the various LED’s behind the screen depending on the picture. This increases the contrast ratio (the difference between black and white) but this can come at a cost. An example is the movie, Stargate Continuum. It opens with a big space scene so the LED’s turn off with the result being that you can’t see most of the stars. They are, however brighter than LCD’s and usually more expensive. There are LED TV’s that are not Dynamic. That is, they just turn on and show that space scene just fine but with less deep blacks. LCD TV’s show the stars, also with less deep blacks. Plasma has no problem with that scene but if it is in a room with lots of light or windows, you see the reflections really well on the screen.
As for close captioning, before buying, ask to see it. I would check to see if the text is crisp and if it turns on and off fast. The scrolling ticker of a sports news channel is good for checking the response time of the LCD pixels. Some look blurry to me.

Get an LCD, they’re much cheaper, and still high quality. As for your closed-captioning inquiry, the TV doesn’t produce it, it is broadcast by the station, or the DVD you’re watching. No TV will display closed-captioning differently.
A surround sound system, while wonderful, is both expensive, and time-consuming to install. If you want to do it right, you’ll have to run cables through the dry walls, screw in your speakers around the room, and configure it. So, it’s really up to you.
